Molecular Engineering of Polytriphenylamine: A Fluorinated Cathode for High‐Voltage, Ultrafast, and Stable Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Fluorination of polytriphenylamine lowers the HOMO energy, enabling high‐voltage operation of the PFTPA cathode. Electron‐withdrawing F substituents stabilize the nitrogen redox center and suppress polarization, leading to fast kinetics. The optimized polymer delivers ∼3.75 V vs.

Prevalence of MSI‐H/dMMR Colorectal Cancer in Japan: Data From the Clinical Study Group of the University of Osaka‐Colorectal Registry

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
Using a multicenter Japanese colorectal cancer cohort from 25 institutions, we analyzed 1464 patients across all disease stages and tumor locations to determine the prevalence and clinicopathological features of MSI‐H/dMMR colorectal cancer. MSI‐H/dMMR tumors accounted for 9.4% of cases overall, were present in 22% of right‐sided colon cancers, and ...

Divergent Synthesis of Möbius and Hückel N‐Heterocycloarenes From a Common Macrocyclic Backbone

open access: yesAngewandte Chemie, EarlyView.
In the divergent synthesis of Möbius and Hückel N‐heterocycloarenes from a common macrocyclic precursor, the annulation reaction dictates topology: Scholl reaction gives Möbius topology, while InCl3‐mediated alkyne annulation gives Hückel topology. The Möbius N‐heterocycloarene is unevenly contorted as revealed by crystal structure, and the Hückel N ...

Translational Gap in Biomarker Discovery: Tumor Surface Markers Rarely Mirror Circulating Levels

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Tumor‐associated cell surface proteins are frequently proposed as circulating biomarkers for colorectal cancer (CRC) based on their high tumor expression. However, many candidates identified through tissue‐based analyses fail to translate into clinically useful biomarkers.
